Great — here are well-regarded boutique hotels and small resorts around Sri Lanka that offer yoga and focused wellness/Ayurveda programs. I’ve listed them by region with a short note on the wellness/yoga offering and a reliable source so you can check current packages and availability.

Central Highlands / Kandy region

• Santani Wellness Resort & Spa (near Kandy) — a purpose-built wellness boutique resort with tailored Ayurvedic programmes, twice-daily yoga (group or private), a full spa/hydrotherapy centre and customised diet plans. Ideal for an immersive wellness break in the hills. (thehotelguru.com)

South / Galle and Koggala area

• Kahanda Kanda (near Galle/Koggala) — a small luxury boutique hotel set in tea/jungle gardens with an on-site yoga shala, daily yoga classes (private classes available), spa pavilion and an emphasis on locally sourced food and relaxation. Good for couples and wellness/light-retreat stays. (thetimes.co.uk)
• Amangalla / Aman group properties in Galle Fort (Galle) — luxury-boutique colonial hotels that commonly offer private yoga sessions and high-quality spa/therapies — more of a luxury-boutique spa experience than a structured retreat, but excellent service and private classes available.

South Coast / Tangalle, Nilwella, nearby beaches

• Anantara Peace Haven Tangalle Resort (Tangalle) — large luxury-boutique resort on the south coast offering Ayurveda consults/treatments and yoga classes; often offered both as a la carte sessions and as part of wellness packages. (Good if you want beach + Ayurveda/yoga.) (pureandcure.com)
• Isolabella Ayurveda Resort (Nilwella / South Coast) — smaller, Ayurveda-focused retreat offering daily yoga classes, personalised Ayurvedic programmes (Panchakarma, detox, rejuvenation) and on-site Ayurvedic doctors/therapists; a true wellness retreat by the sea. (spadreams.com)

West / Boutique beach and small-retreat options

• SerendipItaly / Serendipity-style boutique hotels (south-west coast) — small boutique hotels that run multi-day yoga + meditation + Ayurvedic treatment retreats (programmes listed on yoga-retreat/booking platforms). Good for packaged short retreats combining ocean, yoga and Ayurveda. (bookyogaretreats.com)
• Asiri Yoga Retreat (Galle / Boossa area) — a small, more budget-friendly boutique yoga retreat with regular daily yoga, spa and wellness packages close to Galle. Useful if you want a straightforward yoga-focused beach stay. (travelated.com)

Notes and tips

• Type of experience: some properties (Santani, Isolabella, Anantara) are full wellness/Ayurveda centres with resident Ayurvedic doctors and structured programmes; others (Kahanda Kanda, Aman/Amangalla) are boutique hotels that offer daily/private yoga and spa treatments rather than full medical-ayurvedic regimens. Choose depending on whether you want a full Ayurvedic programme (multi-day, medically supervised) or a lighter wellness/yoga stay.
• Booking & timing: many of these places have limited capacity (boutique size) and specialised programmes that run on specific dates — check availability and whether you need to pre-book Ayurveda consultations or private yoga instructors. I cited the hotel/regional pages above where programme details and bookings are shown. (thehotelguru.com)
• Travel logistics: locations are spread across the island — Kandy (hill country) is cooler and good for detox/retreats; the south coast gives beach + Ayurveda. Plan transfer times between regions (road transfers can be several hours).

If you want, I can:

• Narrow this to a short list for a specific region (e.g., Galle/Koggala or Kandy/Tangalle).
• Compare 2–3 properties side-by-side (prices, what a typical wellness package includes, approximate transfer times).
• Find current retreat dates and sample package prices for any one property (I’ll check live availability/prices).
